Netanyahu is expected to warn US lawmakers about the alleged threat posed by Iran's nuclear program. The Israeli leader has been a strong opponent of a deal between Tehran and international mediators, that would ease up pressure on Iran in exchange for guarantees that it will not develop nuclear weapons.
"I'm leaving for Washington on a fateful, even historic mission. I feel that I am an emissary of all Israel's citizens, even those who don't agree with me. For the entire Jewish people," Netanyahu said, as quoted by the Jerusalem Post.
Earlier this week, the White House stated that US President Barack Obama would not be meeting with Netanyahu to avoid making an impression of interfering in Israel's politics prior to the March 17 elections in the country. US Vice President Joe Biden said he would not attend Netanyahu's speech due to prior travel commitments.
